Metrological quantum-to-classical crossover in the volume of a noisy quasiperiodic lattice
Priya Ghosh, Debarupa Saha, Ujjwal Sen +1
Localization-delocalization transitions have recently been proposed for building a class of efficient quantum many-body critical sensors. This work scrutinizes metrological perform…
Journey in quantum metrology and sensing from foundations to applications: a review
Priya Ghosh, Tanoy Kanti Konar, Debraj Rakshit +2
We present a review on quantum metrology and sensing, from its foundations to current applications. Highlights of the review include consideration of both frequentist and Bayesian…
Resource generation and dynamical complexities in open random quantum circuits
Paranjoy Chaki, Arkaprava Sil, Priya Ghosh +2
Realistic quantum devices are inherently open and often involve environments with memory. Here, we investigate quantum resource generation in two classes of random circuits, namely…
Dynamical Quantum Phase Transitions in Boundary Time Crystals
Sukrut Mondkar, Priya Ghosh, Ujjwal Sen
We demonstrate the existence of a dynamical quantum phase transition (DQPT) in a dissipative collective-spin model that exhibits the boundary time crystal (BTC) phase. We initializ…
